I am setting up hardhat in Linux. I have set up the react app first using these commands.

npx create-react-app react-dapp

cd react-dapp

Then I have installed some hardhat dependencies using this command.

npm install ethers hardhat @nomiclabs/hardhat-waffle \
        ethereum-waffle chai \
        @nomiclabs/hardhat-ether

This all done correctly. Then I have created the hardhat configs and setup.

npx hardhat

Then I have edited the hardhat.config.js file. I have places this.

module.exports = {
solidity: "0.8.4",
paths: {                         
   artifacts: './src/artifacts',  
},
networks: {                 
  hardhat: {
   chainId: 1337                
 }

} }; After that I have created the node.

npx hardhat node

I got this error:

Error HH604: Error running JSON-RPC server: error:0308010C:digital envelope routines::unsupported

Had the same problem. Using Node 17.x and it has an updated openssl that is a a breaking change.

This worked for me because I'm using yarn.

export NODE_OPTIONS=--openssl-legacy-provider

You could also try just using the --openssl-legacy-provider switch on node.

I was able to solve the problem using lts node version using nvm.

nvm install --lts
nvm use --lts

I ran into this exact problem just now, however since I have nvm, my cheap work around is to used node v16 for now.

I was also facing the same problem. However, updating the package.json file worked for me. You will have to update "scripts/start" dependency as shown in the image below: enter image description here

start:"export SET NODE_OPTIONS=--openssl-legacy-provider && npx hardhat node"

This helped me: "npm update --legacy-peer-deps"
